Hi y'all. While visiting a local rock shop, I saw these mammal teeth in a tray labeled "shark teeth," along with actual shark teeth. I wasn't sure of what they were and decided to take them home. Their proximity to another tray of fossil cetacean teeth and their rough similarity (crown-to-root ratio) made me think they could be odontocete. Thanks for any help! @Boesse@Harry Pristis

Requesting Rosel et al. (2021) paper on new Balaenoptera species
Macrophyseter posted a topic in Documents
Not exactly a paleontology-related article, but does anyone by any chance have access to a copy of the recent paper describing the new Rice's whale Balaenoptera ricei? Rosel, P.E., Wilcox, L.A., Yamada, T.K., Millin, K.D. (2021). A new species of baleen whale (Balaenoptera) from the Gulf of Mexico, with a review of its geographic distribution. Marine Mammal Science. 37(2): 577-610. doi:10.1111/mms.12776 -
I'm going through my vertebrate collection and making sure the labels are correct before I start forgetting everything haha. I have here two small bones that I found from the Lee Creek Mine in NC. I collected the white one from the Pliocene Yorktown Fm, a marine fauna. The brownish one was collected from mine spoil, so it could range from Miocene-Pleistocene. I have them tentatively identified as marine mammal phalanges, but these are somewhat out of my comfort zone. Thoughts? I"ve tried to show the two bones from all angles. If better or additional photos or needed,

A beautiful Friday at Stratford Hall in Virginia yielded few teeth, but a curious bone that matches one I collected on another occasion from the same spot. My gut says they are from the ear? Skull somehow? But I can’t find a good match... I’m hoping someone with more experience will recognize. Thanks !

I have here a 3" piece of bone, found in Calvert Cliffs, Maryland. I'm not well-versed enough with these to narrow it down further from marine mammal, and am hoping that these photographs contain some identifying features that may be useful to one more familiar with these. Can it be narrowed down any further?

Hey all, I wrote up some more on our recent paper on the giant dolphin Ankylorhiza (formerly Genus Y) from the Oligocene of South Carolina - this is a bit more interesting as it covers the anatomy, adaptations, feeding ecology, and evolutionary implications of the discovery. Hope you can give it a read! https://coastalpaleo.blogspot.com/2020/08/ankylorhiza-tiedemani-giant-dolphin_9.html- 2 replies

Want to read more about the giant dolphin Ankylorhiza (="Genus Y")?
Boesse posted a topic in General Fossil Discussion
Hey all, Since COVID began and I've had more free time I've been getting back to blogging, and now I'm regretting taking such a hiatus since I started here in Charleston. I've written the first of a 2 or 3 part series of semi-technical blog articles that most here should understand and appreciate on our new study on the giant dolphin Ankylorhiza tiedemani (formerly known as Genus Y). The first post is about the background to our paper, and the second one will be a bit more on the anatomy, feeding behavior, locomotion, and evolutionary implications of Ankylorhiza. Take a read here: -
Hi everyone, This is more of a general question for my own knowledge. I've been trying to determine better how to differentiate between fossil and rock. I know it can be hard at times. I read various posts here to learn how, and I wanted to try my hand at it. I believe these are all fossilized bone found in a Florida river. I know it's almost impossible to identify exactly what they are, but I'd only like to know if they are actually bone. Would anyone be able to tell? Each piece is around 1 inch long.

Hi all - I did not have time in January when I normally write these up, but thanks to Covid quarantine I managed to get some time last month and write up a comprehensive review on my blog of every single 2019 paper in marine mammal paleontology. Enjoy! https://coastalpaleo.blogspot.com/2020/05/2019-in-review-advances-in-marine.html

Blog post: The terrible fossil record of sea otters
Boesse posted a topic in General Fossil Discussion
Hi all - in the hopes of attempting to reach a wider audience, and anyone who has collected possible sea otter fossils, I'm sharing the first two posts from my blog "The Coastal Paleontologist" in a short series on sea otter paleontology and evolution. The first one is mostly a bit on sea otter biology, and the second is the first one that really deals with the paleontology aspect. The third (and fourth?) posts will deal with what the limited fossil record can tell us about sea otter evolution. The sea otter fossil record is quite poor, and I'm hoping that some of you may have found some fossi- 4 replies

I’ve received a chunk of what I believe to be a marine mammal bone from a diatomite mine in the Monterey Formation in Southern California. It is from the late Miocene but I’m not sure what mammal or what bone it is. I know this is a long shot as there isn’t much to go off of but anybody have a clue?

A few more Riker mount displays with macro specimens from the Miocene of Virginia
MarcoSr posted a topic in Member Collections
Below are some more of my macro fossils that I’ve recently put in 16”X12” Riker mount displays. All of the specimens in these displays come from the Miocene of Virginia. The first display with shark/ray specimens, the second display with bony fish specimens, the third display with marine mammal specimens and the last display with reptile specimens. I'm getting some more Riker mount displays Saturday and I'll post some more displays with more of my macro specimens from the Miocene of Virginia. To see a previous post with Riker mount displays with macro specimens from the Paleocene -
Can anyone identify this what type of marine life this skull is part of? I found it today along the East Coast of United States - Atlantic Ocean Spoon in photo for scale. The strange up raised markings on top are perplexing. Type of Eel perhaps? It's wet from me rinsing it in sink. Thank you!

Picked up on beach along with numerous whale verts and bones. Very dense & heavy, with defined (yet worn) ends. Closest match I could find is a dolphin humerus... Any ideas are welcome.

Here are a pair of head-scratchers that I found i at LC. The first is from the Pungo River Fm I thought was a bivalve steinkern, but it is not carbonate, which one would expect in the lime layers of the formation (that, or phosphate, and itisnt phosphate). There is still some matrix on it. So that leaves me with maybe some portion of the bulla/ear region of a marine mammal, but that's purely a guess. The second is from the Pliocene Yorktown Fm, and the material appears to be the same as that of cetacean tympanic bulla. But it doesn't look like one, or like anything Ive seen from

Mammals make up the bulk of my knowledge, but for this specimen I'm clueless. I'm thinking from the locality and the general look of the tooth it could be whale of some sort, possibly a dolphin? Allegedly it was found in Bakersfield California, Shark-tooth hill. I don't own this fossil so these pictures are the best I can get unless I purchase it, what do you guys think it is?

I have a whale bulla and I am hoping to get some ID help with this. It was labeled as a Sperm Whale ear bone but after searching pretty extensively, it looks more like a Mysticeti whale to me. I am far from an expert though so I thought I would post it here and see if anybody has any thoughts on it. It was a dive find in South Carolina. It is a pretty good sized ear bone I think, about 4.8 inches long. Any help would be greatly appreciated.

I recently found a small lot of mammal teeth from Sharktooth Hill. I am doing an education program about marine mammal evolution and they looked like cetacean teeth so I bought them. I am new to fossil forum but not new to collecting marine mammal fossils. I know that you can not get a species ID from cetacean teeth but I am hoping I can get a little additional information or perhaps a suspect so to speak. I believe that the first 3 pictures are of an unidentifed Odontoceti, maybe a Kentriodon of some sort. The first two teeth were both right around 1.5 cm. The third tooth was a li

Coprolite? "A rose by any other name would smell as sweet?!"
InfoHungryMom posted a topic in Fossil ID
Definitely NOT going to do "the tongue test!" I have found many "rocks" that seem to have multiple fossils in them... and this could be one possible reason- it WAS sticky and did contain food at some point? Once again, newbie here.... thoughts? Thank you! -
So a while back, like a year and half or two years, I found one of our more prized fossils in a creek. I had no clue what it was - I mean I knew it was a mammal, but it certainly wasn't a dolphin or anything like that. Later at a PPS meeting, Bobby and Sarah ID'd it as a true seal, p1 premolar. I later decided to showcase it by doing a painting and mounting it along with a drawing of the dentition to show where it goes. Such a great tooth and I've not found any more since. *note: the painting is of a modern day gray seal - it was the closest in dentition that I could find

Hi all! The Mace Brown Museum of Natural History will have a table in the community center this saturday at the Aurora Fossil Festival. I'm currently trying to write up the marine mammal assemblage from Belgrade Quarry, which appears to be transitional between the upper Oligocene Chandler Bridge Formation here in Charleston and the late early Miocene assemblage from the Pungo River Formation in the Lee Creek Mine. Bring your Belgrade marine mammal specimens to our table, I'd like to see them! Several members of this group and the exceedingly generous North Carolina Fossil Club have already don
